If you're having a hard time saying goodbye the the crop as we head into fall you should give the sweater crop a try.
Find a snug fitting knit and show a little less midriff than you might for summer. I found this one on the sale rack at Urban Outfitters - I literally went in looking for something exactly like this.
sidenote: had to sew a liner into the front so my nipples didn't poke through the knit. . . just something to keep in mind ;)
